In this article, we will discuss all possible ways to enable Redmi Note 4, from basic to advanced, taking into account the specifics of the model (Snapdragon 625 or Helio X20 processor, 2/32 GB or 3/64 GB memory versions).
It is important to understand that the algorithm of actions depends on the cause of the problem: if the smartphone just died, it is enough to recharge it for 10-15 minutes; if a firmware error (bootloop), you will need to flash through Fastboot or EDL. We will consider scenarios from simple to complex so that you can independently diagnose and fix the malfunction.
We warn you that some methods (such as working with the Fastboot or disassembling the case) require caution. If you are not sure about your skills, you should contact the service center.
